OK I have to admit I'm not sure if all of those braids are called french braids because some of them you braid 'over' and some 'under' and also e.g. Sakura's bangs braiding is the kind where you only pick hair along on one side, leaving the side framing the face 'clean' ... But my hair lingo ends at french braid, so that's the word I'll use for any type of braiding that involves picking up more hair along as you go. lol But if you know proper names for them, you can always let me know.
I'd also like to take this opportunity to recommend some:
Loose side braid by Maimi Yajima - really simple, but casual cute
Loose twin fishbone tails by Manaka Inaba - fishbone tails (or just one) are really easy to do (just a little time-consuming), but I don't really see them a lot, and loosening them up a bit looks really cute, so I'd rec those for sure.
Twin braids with simply braided bangs by Miyabi was interesting to me because then you could have a cute braided look without using french braids and your hair doesn't even need to be very long. Also Miya gives a lot of helpful advice like if your hair is short you can use wax to help the process, and she shows where you could but ribbons to make the style look even cuter, etc.
Both Eripon and Sakura's braiding of bangs seem universally useful for making one feel just a wee bit prettier. Only those with a really short hair cut won't be able to use them imo.
Also I really want to go to a hairdresser now lol my tips are a mess.
